Crow is a hexapedian, thus he has two arms, two legs, and two wings which can be folded behind his back. Their total span is about 4 metres (12 feet). Since he is a werecrow, he can change himself to a more-human or more-feral form at will, though most of the time he prefers to remain in his anthro form because he feels most comfortable in it.

He can also manifest parts of one form while appearing in a different one (for example, growing the wings on his back whilst being in human form). He also is the stepbrother of Krowy, and the two share a close, fraternal relationship in real life.

Werecrow has been a feathery for most of his life though it was in 2005 where he discovered that his personality can be strongly associated to that of a Crow, thus his feathersona Marcel Crow, was born. He couldn´t find a proper term for this until he discovered the fandom on the internet around the same time.
Sometime in 2007 he found out that his connection to Crows is a characteristic that would declare him a therian.

Werecrow is a fan of roleplaying and videogames in general. He founded and runs the "Crow Conglomerate", a deviantART club focusing on corvid art.
